Web8 jun. 2024 · ” The phosphate group is negatively charged, making the head polar and hydrophilic, or “water loving.” The phosphate heads are thus attracted to the water molecules in their environment. The lipid tails, on the other hand, are uncharged, nonpolar, and hydrophobic, or “water fearing.” WebSmall uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot. Charged molecules, such as ions, are unable to diffuse through a phospholipid bilayer regardless of size; even H+ions cannot cross a lipid bilayer by free diffusion.
